Novel applications of metal-organic frameworks (MOFs) as redox-active materials for elaboration of carbon-based electrodes with electroanalytical uses

Metal-organic frameworks are novel materials with specific pore-size that presents unlimited applications in material sciences. The presence of metallic ions in the MOF structure offers a redox active material with electrocatalytical properties towards diverse biomolecules, organic compounds and heavy metals. This property can be combined with nanomaterials for create cheap carbon based electrodes with enhanced electroanalytical features (like selectivity, good low detection limits and high stability on alkali or acid media). In this review, we have collected recent information about MOF applications in carbon electrodes and fundamental aspects on the electroactive MOFs design, fabrication of MOF-modified carbon based electrodes, characterization of electrodes and examples of direct sensing with MOF-modified electrodes.
